Abstract

This increases the likelihood of online electronic payments being processed. [Solution] The terminal device 1[q] includes an information acquisition unit 112 that acquires two types of tokens KK[q] from the payment device 3: an online token KX[q] used in electronic payments performed when the payment device 3 and the terminal device 1[q] can communicate, and an offline token KY[q] used in electronic payments performed when communication between the payment device 3 and the terminal device 1[q] is difficult; and a display control unit 114 that displays a code image GG[q] on the display device 13 based on one of the two types of tokens KK[q], which is determined according to the online token response waiting time TSWX[q] based on the memory capacity α of the terminal device 1[q].
